Oh I totally agree here. Soft-clipping is useful when the level is
generally below 0 dB FS with only a few spikes in the 0-6 dB range.
Beyond that you definitely need something else. However, I think the
idea should be to avoid getting there in the first place (using the spec
and/or a limiter).

Well, why not have a hardcoded limiter that cannot be overridden? Sounds
like it would provide higher quality with no way to "cheat the system".
This would prevent loudness war and "ads are so loud" issues right from
the start. The compressor could still be used an an optional "effect"
but the clipping issue would be avoided as part of the design itself.
